This paper describes a short ion flow activity that can be completed within one lab or lecture session. The activity is focused on the core concept of flow-down gradients and is geared toward undergraduates. No previous knowledge of equilibrium potentials or membrane potentials is required. Students are guided through a set of questions that build…

Conceptualizing the nature of science (NOS) is a crucial component of science education, as it facilitates students' comprehension of how scientific knowledge is developed. Unfortunately, teachers can themselves hold inaccurate views of NOS or assume students can infer NOS ideas from instruction or by undertaking experiments. Building on previous…

A mixed methods study was used to investigate the influence of blended learning on preservice teachers' readiness to teach using inquiry-based learning. Online science teaching methods activities were added to a face-to-face science content class for the preservice teachers to improve their readiness to teach using inquiry-based learning. An…

Stereotypical imagery of scientists is detrimental to effective and inclusive science education. Many elementary pre-services teachers often hold onto these images, creating an unconscious bias limiting their effectiveness to both teach science content and discourage some groups from entering the scientific field. Proactive and targeted…

We assume the existence of conceptual profiles as a manifestation of pluralism in science education. This means recognizing the heterogeneity of thinking and speaking, that is, the coexistence of two or more meanings of the same word or concept that are accessed and used by the individual in appropriate contexts. Science is not a homogeneous way…

Computational thinking (CT) is becoming increasingly important for K-12 science education, thus warranting new integrations of CT and science content. This intervention study integrated CT through unplugged, or handwritten, algorithmic explanations of natural selection. As students investigated natural selection in varying contexts (specific and…

Science knowledge is deeply intertwined with human values, ethics and societal needs. While science is often perceived as value-neutral, the authors argue that the intertwined nature of science and values can be modelled from the early stages of education. This article shares examples of how individual, collective, and planetary values can shape…

Medicinal chemistry is a core course for undergraduate students who major in pharmacy, where complex drug structures and abstruse concepts often pose significant challenges for students. As an important supplement to classroom teaching, online teaching resources have demonstrated the ability to enhance students' interest in learning and improve…

Early science inquiries and experiences increase young children's awareness and interest for science. The importance of promoting science process skills which bolster children's confidence to formulate and communicate personal ideas have been emphasised by international guidelines. As Loose Parts Play (LPP) is a form of free play involving…

When preschool teachers attempt to initiate play-responsive science teaching, opportunities arise to develop or challenge the play further, for example, by introducing or focusing on science content. The aim of this article is to generate knowledge about how projected images and videos can be used in attempted play-responsive science teaching and…

The main objective of this four-year empirical research project has been to develop the experimental design skills of 12-16 year-old Hungarian pupils in Grades 7-10 of junior high school through guided inquiry, using six chemistry experiment worksheets each school year. Group 1 (control group) and Group 2 follow step-by-step instructions, but…

Traditional assessments in undergraduate psychology often prioritise technical accuracy over creativity. In response to growing calls for more inclusive, flexible, and student-centered pedagogy, this article presents two case studies on the use of the 'unessay' in mid-level undergraduate psychology courses. The unessay allows students to…

We live in a world marked by a crisis that we understand, from post-colonial literature, as a crisis of the knowledge model that underpins Western Modernity. Therefore, science education which deals with the study of the production of scientific knowledge needs to be attentive to this question. We argue that the challenges imposed by the crisis…

A derivation of the conservation equations for fixed bed tubular reactors in cylindrical coordinates is presented and a differential operator for the substantial derivative in porous beds is introduced. The emphasis on the distinction between the functions of the void and volume fractions in the derivation of the conservation equations sets the…

In the environment, communication among microorganisms is a key aspect of their lives. Through communication, single cells of a microbial population can coordinate their gene expression and, in consequence, their physiology. Quorum sensing systems (QS) are one of these mechanisms that allow this communication through the production and detection…
